They text their friends all day long. At night, they do research for their term papers on laptops and commune with their parents on Skype. But as they walk the paths of Hamilton College, a poster-perfect liberal arts school in this upstate village, students are still hauling around bulky, old-fashioned textbooks — and loving it, The New York Times reports. “The screen won’t go blank,” said Faton Begolli, a sophomore from Boston. “There can’t be a virus. It wouldn’t be the same without books. They’ve defined ‘academia’ for a thousand years.” Though the world of print is receding before a tide of digital books, blogs and other Web sites, a generation of college students weaned on technology appears to be holding fast to traditional textbooks. That loyalty comes at a price. Textbooks are expensive — a year’s worth can cost $700 to $900 — and students’ frustrations with the expense, as well as the emergence of new technology, have produced a confounding array of options for obtaining them. Internet retailers like Amazon and Textbooks.com are selling new and used books. They have been joined by several Web services that rent textbooks to students by the semester. Some 1,500 college bookstores are also offering rentals this fall, up from 300 last year. Here at Hamilton, students this year have a new way to avoid the middleman: a nonprofit Web site, created by the college’s Entrepreneur Club, that lets them sell used books directly to one another.
